Humanity is the most dominant species on Futurama, their exact importance in the Universe can be disputed, given their often enslavements of other races, such as the Omicronians and Decapodians, and at least one other race in the past that paired off the smartest humans and forced them to mate for unknown purposes. They remain an important member of the Democratic Order of Planets. The DOOP Army is mainly made up of humans. Human milk and meat are available, and other human-based products include Soylent Cola, Human Broth and Glagnar's Human Rinds. Human noses, known as "Human Horn", are considered an aphrodisiac, but their use for this purpose is highly taboo.
